SOLUTION: The toner carrying path tube 43 is constituted of a first carrying path tube 45 fixedly fitted to the attachment and detachment unit 2 side and a second carrying path tube 46 fixedly fitted to the toner supply device 40 side while being divided at a halfway position between the supply device 40 and the developing device 14. The divided end part 45a of the tube 45 is separated from or coupled with the divided end part 46a of the tube 46 in accordance with the attachment and detachment action of the unit 2. |
